    Hi all I'm new here and haven't found a couple answers I'm looking for so if it's already answered please let me know.

    I'm planing on doing a 6dof motion simulator. I already have PC and controllers. I have a fairly limited budget (<$3k) and power (120v 15amp) at my apartment so will have to stick to low power solutions like dc 200w-300w worm drive motors. I'm planning on making a system for flight and racing sims.

    Questions:
    1) How important is speed of motion vs distance of travel? I don't need to feel every pebble in the road as I think a tactile transducer will handle higher frequancy motion better. Is this a fair assumption?

    2) How important is it to have the riders CG aligned with the point of rotation? The idea being that for rotation it would be better to rotates the rider and not tilting the platform to the side. Not sure if that makes sense.

    :)

    1) In my view speed and accuracy of movement are particularly important if VR is to be used with motion, as the worst thing you can have in VR is lag between what you see and what movement your brain expects.

    2) See @SeatTime's comment here that it is important to align them: http://www.xsimulator.net/community...tors-mms-and-arduinos.6948/page-21#post-96569

    Good point. Yes VR will be used not a monitor. Yeah accuracy is very important. I would like a clean experience.

    When you say speed do you mean response time or the speed the simulator moves. I assumed the speed of motion would produce larger simulated effects/g-forces no?

    Regarding #2. thanks for the link that was the exact answer I was looking for. Looks like my assumption was correct. :D

    By speed I mean the linear speed of what you use to drive the simulator, it can be a bit subjective but generally speaking above 200mm+/sec is a good ballpark if you are considering VR, of course design also matters: http://www.xsimulator.net/community/faq/speed-needed-for-good-motion.218/
